Strawberry diseases and treatment methods, photos

A fairly common strawberry pest is the spittlebug. This pest sucks juice from the very core of the plant. It can be spotted by the appearance of a foamy film in the center of the plant. This is the pest's way of protecting itself from the sun by secreting its saliva.

There are several methods for controlling this spittlebug. Go over the entire strawberry plantation, collecting and destroying the mite. It's quite large and easily visible. Another method is to make a solution of potassium permanganate and pour it over the strawberry bushes with hot water (60-70 degrees Celsius). This treatment is always beneficial for strawberries, even during flowering, and does not cause any harm. However, it's best to use this method in the evening. It's important to remember that it's best to pour cooler water (45 degrees Celsius) on young plants. Please note: Tips from experienced gardeners on growing strawberries.

The strawberry spider mite is very small and invisible to the naked eye. It lives under the leaves and sucks the sap. This greatly weakens the plant, causing the leaves to curl and the bush to shrink. If this pest becomes widespread, the leaves turn yellow and then die.

You can combat it the same way as in the first case: with boiling water. You can also treat it with colloidal sulfur or Nero. However, these are pesticides and should only be used after the harvest is complete.

Strawberry brown spot

A preparation that can be prepared at home: for 10 liters of water you need 5 grams of potassium permanganate, 1 bottle of iodine, 20 grams of soap and 2 tablespoons of soda.

Treatment can also be carried out with a copper preparation or Bordeaux mixture. If the infestation is widespread, then Oxychom, Ridoml, or Skor can be used. This treatment is necessary because after a widespread infestation, the fungus can destroy 60% to 100% of the leaves, preventing the plant from receiving adequate nutrition, which in turn leads to the death of the leaf blade and eventually its death.

Signs of this disease include dark spots on the leaves, as well as on flower stalks and runners. Initially, these resemble dried-out leaf edges, but later, dark pads appear on the leaf tip—this is the fungal mycelium. The causes of the fungus' spread can vary, including excessive moisture and insect pests that carry the disease.

Black and late blight rot

The pathogen develops very quickly on rotting food, forming dark-colored, spherical zygospores in plants. Reproduction occurs rapidly at high temperatures and relative humidity levels above 85%. Treatment is necessary. treating strawberries in spring against diseases and pests.

You can avoid these diseases and not protect against this disease with chemicals if you grow strawberries in an upright position.

Another disease is late blight. It reduces yield by at least 15%, and in some cases, the entire crop is lost. This disease attacks everything above ground: leaves, growing points, inflorescences, buds, and the berries themselves. Berries are particularly affected, developing brown, hard spots. These berries are inedible; they taste bitter.

Methods of control: crop rotation, proper watering and quality fertilizing, planting healthy seedlings.

Fusarium wilt

What is needed for strawberry disease (photo and treatment) - Fusarium wilt? When this disease occurs, redness appears in the center of the bush. If it becomes chronic, the leaves become cup-shaped, turn gray, and then wither and dry out. Fruit production is low or nonexistent. This disease can completely destroy the strawberry plant within a few years.

The degree of infestation depends largely on the climate, the level of agricultural practices, and the maturity of the seedlings. This disease often attacks plants in patches, which is associated with the low-lying soil where strawberries are grown. Contaminated soil can also be a source of infection, and this disease is common in strawberry plantations where strawberries have been growing for a long time.

Good agricultural practices make seedlings more disease-resistant. Disease-free planting stock and proper crop rotation are also crucial. If outbreaks appear in the area, infected bushes must be removed.

To reduce the severity of the disease, you can take certain protective measures: apply a large amount of potassium oxide and lime to the soil. Mulch the area with black vinyl film. Proper care is essential. caring for strawberries after harvesting.

Verticillium wilt and other fungal diseases

How can I recognize the signs of strawberry disease (photos and treatments)? When a plant contracts verticillium wilt, the petioles initially turn red, especially in the final stages of growth, and the bush becomes flat and stunted (dwarfed). The lower leaves are the first to become infected, and then the entire bush. If the soil is sandy, the plant may die more quickly; if the soil is loamy or sandy loamy, the disease will occur more slowly.

If the disease is caused by ascomycete fungi, the entire plant is affected: leaves, berries, and even roots. This disease can affect all plants growing in the garden. The fungus develops rapidly during frequent rainfall and warm weather. It can be introduced through previously infected seedlings, through watering, on tools, and even on vehicle wheels.

Signs of the disease include brown spots on the leaves, which eventually begin to crack. The affected leaf does not dry out but serves as a source of infection. The shoots are also affected by brown spots with light centers. On the berries themselves, the spots are initially small and water-soaked. However, as the disease progresses, the spots begin to grow and darken. These berries should not be eaten.

In the early stages of the disease, fungicides such as Ridomil, Quadris, and others can be used. Once the disease has become severe, spraying with Bordeaux mixture is necessary.

Nematode is a strawberry pest

Severely infected plants resemble broccoli. The leaves become twisted, the petioles become shorter, the runners thicken, and the flowers become distorted and misshapen. Naturally, the berries, even if fully ripe, are completely tasteless and distorted. When the rainy season arrives, the nematode proliferates.

We recommend:Mixed vegetable planting patterns and combinations

Agronomists recommend treating strawberries with a biological product called Nemabact. Planting marigolds near strawberries is a good option. They prevent nematodes from multiplying. While the nematode won't go away if it's already present, it won't spread.

Many people are interested in the development of fungal diseases of strawberries, including photos and treatments for brown spot. This is a well-known and widespread disease that destroys up to 50% of leaves, significantly weakening the plant. It is caused by a fungus called Marssonina petontillae.

The disease manifests itself as large spots on the leaves, often appearing towards the end of summer. Initially, these spots are reddish in color, then turn completely brown, giving them a withered appearance. Strawberry brown spot severely impacts the formation of generative buds, leading to a significant reduction in yield the following year.

How to combat this problem? First and foremost, it's important to grow varieties that are resistant to this disease. But if it does happen that your strawberries are infected, experts recommend a product called Gamair. It's also important to practice proper farming practices and take preventative measures to prevent fungal disease. To do this, spray the area in the fall with a product called Ordan, Falcon, or Metaxil.

Different types of weevils

How to combat these insects? When buds begin to form and immediately after harvesting, the strawberry plot should be sprayed with a 3% malathion solution: 30 grams of the solution per bucket of water. In the fall, plant debris should be destroyed and the space between the rows should be loosened.

The nettle leaf weevil is another pest, green in color and with a wide but short proboscis. This insect eats the edges of leaves. When flower stalks begin to emerge, the weevils pupate. The larvae remain in the soil over the winter, and by late summer they damage strawberry roots.

How to control it? Growing the crop in the same area for more than four years is not recommended. Loosen the soil before it flowers and after harvesting. Also, treat the plants with a prepared 50% malathion solution, 30 grams per bucket of water. plant strawberries under covering material.

Causes of strawberry disease

Strawberries sometimes wilt. This could be due to insufficient watering, but it could also be the result of root damage from mole crickets or moles. There are many insecticides available to combat mole crickets, which should be applied to the planting hole when planting.

Strawberries are rotting. There are several reasons for this. Most often, it's caused by fungal diseases triggered by high humidity. They can also rot due to dense plantings and poor ventilation. Rotten fruit should be removed. It's also a good idea to take preventative measures once the first berries appear: mulch the entire area with sawdust to prevent the berries from touching the ground.

To prevent strawberries from becoming diseased, it is necessary to comply with all agricultural practices and apply root and foliar feeding on time, so that the plant remains healthy and tolerates diseases more easily.
